Jogil..Just a quick measurement..Could be more accurate with time spent on it....Measured distance across perforation holes in the middle of the stamps...Just my opinion.
It appears that the BEP was using two different hole sizes from 0.040" to 0.042" as the older perforators from George C. Howard (0.040") were being gradually replaced by newer perforators from Universal Telegraphic (0.042").
